IMPROVEMENT IN EJ-ECTORS FOR OIL-WELLS.

Specilieation formingparl of Leiters Patent No. 44,587, dated October 1l, 1864.

To all whom it may concern.:

Be it known that we, J. D. Ancien and FREDERICK CRooKER., oi' Titusville, Crawford county, and State of Pennsylvania, have invented a new and useful Apparatus for Forcing up Petroleum and other Liquids from Deep lVells; and we do ,hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is an elevation ot' our said apparatus in awell; Fig. 2, a vertical section of the apparatus; and Fig. 3 a cross-section thereof, taken at the line A a of Fig. 2.

Our invention is intended chiefly for raising petroleum from deep wells, although it is applicable to the raising oi' other liquids from great depths.

In the accompanying drawings, a represents a well, andi) a pipe, the lower end of which extends down to within a short distance of the bottom thereof, and the upper end above the well is connected with a horizoutal branch pipe, c. leading to any suitable receptacle for the oil or other liquid to be raised. Near the lower end of this pipe there is a sudden contraction, d, and from this contraction it gradually enlarges in the form of ahollow frustuin to a larger diameter than above the contraction, the lower end being open. Another pipe, e, from above the well, extends down alongside of and parallel wit-h the pipe` I). The upper end branches oli", as at f, to forni a connection in. any suitable way with an air-pump-that is, with an)Y suitable pump capable ot' forcing. aii` into and down through the said pipe c. The lower end oi this pipe is bent up like a Siphon, as at g, and extended into the llower and enlarged partof the pipe b, and the upper end of the part thus turned up is made conical, as at 71, with radial spursA fi projecting from thejperiphery at or near the base of the cone, so that when inserted there shall be an annular space between the said cone h and the conical under part of the contraction d of the pipe b. The bore of the pipe e, which we term the blast-pipe, we prefer to make one-third less 1n diameter than the discharge pipe l above thc contraetion d; and for awelliive hundred feet in depth and four and a half inches bore, in which we have success-fully worked our said invention, we have made the bore ofthe blast-pipe c one inch inl diameter and the bore of the dis charge'pipe one inch and a half in diameter. In the saine apparatus we made the contrae tion d in the discharge-pipe b five-eighths of an inch in diameter, gradually enlarged ina conical fornito two inches,vand of that diameter to the lower end; and the bore of the blast-pipe e was contracted at the discharge end ot' the conical part h to about one-half oi' an inch in diameter, and this we term the blast-nozzle. XVith the above proportions we have successfully raised petroleum from a depth oi' i'ive hundred feet; but we do not wish to'be understood as limiting ourselves to such proportions. The tube-pipes b and e a re bou nd together and held atthe required distance apart by cross-plates k k, through which the57 pass; and when placedin position in a well the surface-water is prevented from running down into the well by the usual and welt known packing heretofore employed for the purpose, interposed between the bore-of the well and the outer diameter of the pipes b and e. The apparatus being thus constructed and located, the horizontal brauch c ot the pipe I: placed so as to discharge in a suitable receptacle, and the upper end of the blast-pipe 1' connected with some suitable air-pump, and air being thereby forced linto the said blast` pipe, it will esca-pe under a pressure proportioned tothe force oi' the blast in an upward .direct-ion 'from the nozzle h into thc conical part of and just below the smallest part ofthe contraction. This induces a current of the oil or other liquid from the bottom-of the well -upward in the annular space between the lower part of the pipe 7 and the nozzle of the blast-pipe, and when it rises above the contraction d it is lifted and carried upward by the force of the blast of air below it. In this way' we are enabled to force oil and other liquids from the bottom of very deep wells without the use of pistons or valves, while at the same time the force applied does not tend to choke the ways or passages through which the liquid is supplied to the well.

W'hzxt we claim as of om invention,m1d dethereof, vslllmiani'nlly es and for the purpose sire to secure by Letters Patent, is-

The dischargepipe, with its contraction :u1 Il open lower end, substantially as described, in combination with the blnsbpipe, having its lower end turned up und provided with a nozzle, and inserted in t-he lower openend of the e discharge-pipe und below the cont-motion J.
